How many windmills would you need to produce as much power as one average nuclear power station?

Okay we are assuming that the wind is blowing.
Update: Okay it was a pun on the word but seriously how many would you need?
Update 2: I wonder how much area 7000 windmills would take up... that's got to be a lot. Can you imagine the noise and threat to wildlife?
